in regards ti the following ""Error" message

 

Application Error

A Fatal error occurred:

'-500' is not a valid value for property width.

I get this when I attempt to open P2ATC

I can delete my 
"settings and it will open (of course I have to re do all setting) however when I close the program and shut down computer, the re open the Error message prevents it from opening. I assume I need to find what is causing this error on my computer and fix it, SO any ideas on what is causing and how to fix it??
